Volume is L x W x H
8 x 10 x 3 = 240 cubic units
Answer:
a. 11x + d
b. 15m + 10n
Step-by-step explanation:
a. 2(4c+5d) + 3(x-3d)
Break the brackets:
2*4c + 2*5d + 3*x - 3*3d
= 8x + 10d + 3x - 9d
Collect like termsL
= 8x + 3x + 10d - 9d
= 11x + 1d
b. 6(3m+n) - 4(m-n)
Break the brackets:
= 6*3m + 6*n - 3*m - 4*(-n)
= 18m + 6n - 3m - (-4n)
= 18m -3m + 6n + 4n
= 15m + 10n
Hope this helped :3
Answer:
To find the area of a rectangle we use the formula:
L x W
Replace those with it's actual value
4 3/4 x 3
19/4 x 3 = 14.25, 14 square inches is the area
Answer:
-7
-4/21
400
Because 13 times 7 is 91..so -7
-3/7÷9/4 becomes -3/7×4/9. Taking LCM and solving gives -4/21.
last is easy.it becomes (12÷3)×100=400
